Re: [Veritas-bu] Tuning Settings on NetBackup Client (Windows)

Hi Simon,

I think they control everything (top->down) as I recall testing this in the past once the master was changed; it altered the buffers on all of the media servers.

Likewise, if you have a DSU on your master, you could also benefit from the following:

SIZE_DATA_BUFFERS_DISK

I recommend the following (gathered mostly from white papers/etc. for top performance for LTO-3/4/5 drives)

NUMBER_DATA_BUFFERS: 32

NUMBER_DATA_BUFFERS_RESTORE: 32

SIZE_DATA_BUFFERS: 262144

SIZE_DATA_BUFFERS_DISK: 262144

Having said that, I also have the exact same touch files (UNIX) on the media servers.

Justin.

All,

Following on from the documentation below, can I just ask, that if I want to improve performance on a Windows 2003 client, where the backup is done on the LAN, if I follow this document, am I right in thinking, these settings should be put in place on the MASTER Server as well?

http://www.symantec.com/business/support/index?page=content&id=TECH19206

I ask, because the document talks about a Media Server, which a Master Server could well be, and in this environment, I have one master that does ALL the backups.

Reason I am looking at this, is to try and improve backup performance for the LAN, but it is a Windows client.

Thanks, Simon
